HINGE Specification of Letters Patent.

Patented Aug. 13, 1907.

Application tiled October l, 1906. Serial No. 336,995.

To all whom it may concern:

Be it known that I, CHARLES J. AEBI, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented new and useful Improvements in Hinges, of which thefollowing is a specification.

My invention relates to improvements in hinges, particularly thoseadapted to carry heavy bodies into position, as the doors of safes,vaults and the like.

The object of the invention is two-fold, iirst to enable such bodies tobe swung upon the hinges by the expenditure of a small amount of force,while providing an inexpensive, durable mechanism to that end; andsecond to secure adjustment, usually vertical, of l5 the body in thedirection of the length of the hinge pintle.

In the particular embodiment of Ymy invention selected for illustration:Figure l. is a front elevation of a vault, with the door closed, saiddoor being swung upon the usual crane hinge, having four true hinges.Fig. 2. is an enlarged view of one of these hinges, in axial section.

Referring to the drawings, A represents the vault frame, B the swingingbody or door, and C the hinge crane. Hinges l and 2 provide means ofswinging the door B freely on the crane C, While hinges 3 and 4 attachedto the frame in any suitable manneras by capscrews a4, provide means ofswinging the crane C freely on the frame A. Freedom and ease of movementis therefore provided at all points, and adjustment of either pair ofthe hinges, l and 2 or 3 and 4, will raise or lower the door B.

As the hinges are similar in all essential particulars, I will describeone only, and have selected the one designated as 4. It will be seenthat one leaf or plate a carrying the knuckle al is rigidly attached tothe frame A, while the other leaf or plate c, carrying the knuckle c1 isa part of the crane C. Between the two knuckles al and c1 may beinterposed a washer W, but it has no other use than to give a morepleasing finish to the hinge. Both knuckles a1 and c1 and the washer Ware formed, or bored axially, to receive a pintle D, which extends acontrolling distance into each knuckle and upon which the door swings,Pintle D is preferably a solid cylinder, the planes of whose ends are atright angles to its axis, made of a tough untempered steel or the like.Plugs d, (Z are cylindrical, with the plane of one end at right anglesto the axis, which end seats upon the end of the pintle, and the otherend rounded or otherwise shaped to minimize friction. Other plugs d2, d3similar in shape, are placed with their rounded ends abutting andresting against the rounded ends of the plugs d1 and d respectively. Allthese plugs are made of tempered or hardened metal to withstand wear.The outer end of each knuckle bore is threaded to receive a set-screwd4, d5, whose outer end is square or otherwise formed for wrenchContact, and whose inner end is a plane at right angles with its axisand adapted to seat firmly against the similarly shaped ends of theplugs d2 and d3, respectively.

Oil holes may be provided in any convenient manner. An efficient form isthe slanted holes a2, c2 stopped against the entrance of dust by thescrew plugs, a3, c3, respectively.

The operation is as follows: If it is desired to raise the body, as B,whose weight is being sustained, all the parts of the hinge being in theposition shown in Fig. 2, tighten the set-screws (l4 and d5 eachone-half the required amount, the aim being to maintain the pintle insuch a position that it extends into each knuckle the same distance.When the door is too high, and is to be lowered, turn the set-screws theopposite way. The weight being carried on the rounded head of (l1, andthat of the plug d2 where it contacts with the rounded head of (Z1, andthat of the plug (l where it contacts with (Z3, friction will beminimized and very heavy bodies will be easily swung out of and intoposition. These hardened plugs being thoroughly lubricated, will bedurable, and the wear may be taken up with the set-screws in the mannerdescribed.

Various changes of parts, would lie within the scope of my invention, asfor example, omitting the bearing plugs d, (l1, d2, and d3, making theends of the pintle D, and the -inner ends of the set-screws d* and d5round- .ed and the parts of hardened metal; also any shaping of the endsof plugs, pintle, set-screws or their equivalents, so as to makesuitable bearing surfaces.

I claim as my invention and desire to secure by Letters Patent of theUnited States:

An improved'hinge comprising co-acting members having knuckles withhores extending therethrough and adapted to register, a pintle of toughuntempered metal extending across the joint between the knuckles whenassembled, said pintle having its opposite ends squared, bearing blocksat each end of the knuckles, said blocks being ot' tempered metal havingone end squared to fit against the corresponding end o1' the pintle` andhaving the other end rounded, screws entering the outer ends of eachknuckle and havingl fiattened inner ends, und other bearing blocksbetween the iirst named blocks and the inner ends of the screws, saidother blocks having one end rounded and in contact with the rounded endof the first named blocks and having the other end flattened and engagedby the inner flattened end of the screws.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CHARLES J, AEBI.
